Description

Technical Field

[0001] The utility model relates to the technical field of anode sampling in pre-baked anode production operations, in particular to a device for turning over an anode sampling clamp. Background Art

[0002] With the rapid development of the electrolytic aluminum industry, the production capacity of pre-formed anodes has increased significantly, resulting in increasingly higher requirements for the quality of pre-formed anode products. Improving product quality requires constant product testing to identify deficiencies and improve the quality of pre-formed anodes. Currently, anode sampling is performed from the second carbon bowl directly above the anode. This single testing location does not allow for a thorough assessment of the overall anode quality, hindering product quality improvement. To achieve multi-point testing of the anode, it is necessary to flip the anode over or take samples from the side to assess its overall quality.

[0003] At present, sampling can be done by simply lifting the selected carbon blocks with a clamp to the sampling area. The anode cannot be turned over, and it needs to be turned over manually by lifting it and then using a crowbar. Therefore, the risk factor is high, the sampling workload is increased, the labor intensity is high, the work efficiency is low, and the carbon blocks are damaged. Especially when the output is high and the quality fluctuates, the number of sampling times increases and the work becomes more difficult.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a device for flipping the anode sampling clamp. Utility Model Content

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figures 1 to 2 As shown;

[0047] This embodiment discloses a device for flipping an anode sampling fixture, the device comprising:

[0048] clamp lifting arm 1; and

[0049] A shutter assembly integrated into the clamp lifting arm 1, the shutter assembly comprising a shutter 401 located at the upper end of the clamp lifting arm 1, and a shutter base 402 located at the lower end of the clamp lifting arm 1, and a mounting bracket 3 is provided at the lower end of the clamp lifting arm 1;

[0050] A clamping plate 201 is provided at the lower end of the clamp lifting arm 1 and at the position cooperating with the mounting bracket 3, and a grabbing pin 202 is installed in the center of the clamping plate 201. Bearings are installed on the axes of the grabbing pins 202 of the clamping plates 201 on both sides;

[0051] The device clamps and fixes the eccentric position of the anode by means of the gripping pins 202 of the clamping plate 201 so as to drive the anode to turn 90 degrees under the action of its own weight.

[0052] Specifically, this embodiment discloses a device for flipping a clamp suitable for anode sampling, which includes a clamp lifting arm 1 and an opening and closing assembly. The opening and closing assembly of this embodiment moves along with the clamp lifting arm, and the lifting arm can also maintain the clamp lifting arm 1 in an open state under the action of the opening and closing assembly. In addition, the opening and closing assembly can not only keep the clamp lifting arm 1 open when in a closed state, but also raise the clamping end to facilitate subsequent flipping during anode sampling. The device of this embodiment improves the size of the existing gripping pins by increasing their diameter and length. At the same time, bearings are installed on the gripping pins 202 on both sides to provide power for rotation. The clamping plate 201 of this embodiment adopts an eccentric positioning clamping method when clamping the anode with the gripping pins, so that the gravity of the anode can be used to naturally flip toward one side during sampling to achieve the flipping effect.

[0053] Preferably, the clamp lifting arm 1 of this embodiment includes two lifting upper arms 101 and two cross-arranged lifting lower arms 102; the lifting upper arms 101 are hinged to the corresponding lifting lower arms 102, and the upper ends of the two lifting upper arms 101 are installed with openers and closers 401; the lower parts of the lifting lower arms 102 are bent toward the inner side of the clamp lifting arm 1 to form a bending portion 103, and the end of the bending portion 103 is installed with a splint 201.

[0054] Preferably, the mounting bracket 3 of this embodiment includes a bracket body 301, a bracket upper connecting portion 302 formed on the upper portion of the bracket body 301, and a bracket lower connecting portion 303 formed at both ends of the lower portion of the bracket body 301;

[0055] The bracket body 301 is movably connected to the middle position of the lifting lower arm 102 on the corresponding side through the bracket upper connection part 302;

[0056] The bracket lower connecting portion 303 is slidably connected to the bracket body 301, and the bracket lower connecting portion 303 can move along the horizontal direction of the bracket body 301;

[0057] The bracket lower connecting portion 303 is connected to the bent portion 103 .

[0058] Secondly, the middle portion of the upper surface of the bracket body 301 of this embodiment has a shutter base 402;

[0059] The base 402 of the shutter is provided with a locking groove, and a baffle is provided in the locking groove;

[0060] The shutter 401 is provided with a locking rod, and the end of the locking rod is a locking head 403 that cooperates with the locking groove and the baffle;

[0061] The locking rod of the shutter 401 is rotatable relative to the shutter 401;

[0062] When the lock head 403 rotates to the position where it cooperates with the baffle, the shutter 401 and the shutter base 402 are in a locked state;

[0063] When the lock head 403 rotates to a non-matching position with the baffle, the shutter 401 and the shutter base 402 are in an unlocked state.

[0064] This embodiment further defines the specific structure of the mounting bracket 3, as well as the connection method between different components and different positions of the mounting bracket 3 and the clamp lifting arm 1. Since the clamp lifting arm 1 is opened or closed along with the lifting of the overhead crane, this application also needs to consider providing sufficient height for the anode flipping. Therefore, this application increases the original height of the clamp by 300 mm to provide sufficient space for the flipping and rotation of the anode carbon block.

[0065] At the same time, based on the scissor-like opening and closing movement of the clamp lifting arm 1 under the action of the overhead crane, the mounting bracket 3 of this embodiment is divided into three main parts: the bracket body 301, the bracket upper connection portion 302, and the bracket lower connection portion 303. At the same time, to facilitate operation and position adjustment, a handrail 304 is provided on the side of the bracket body 301. The mounting bracket 3 is connected to the middle position of the lifting lower arm 102 via the bracket upper connection portion 302. The connection portion needs to reserve sliding space so that it can have both a hinged function and can slide when the position of the lifting lower arm 102 changes. Similarly, the connection method between the bracket lower connection portion 303 and the bracket body 301 also needs to adopt a sliding connection method. This is mainly to adapt to the adjustment of the relative position of the bracket lower connection portion 303 and the bracket body 301 when the lifting lower arm 102 moves.

[0066] Preferably, a crane hoisting ring 5 is installed at the upper end of the shutter 401 of this embodiment.

[0067] Preferably, the shaft of the grasping pin 202 on one side of this embodiment is installed with a rolling bearing, and the shaft of the grasping pin 202 on the other side is installed with a thrust bearing.

[0068] Preferably, the gripping pins 202 of the clamping plate 201 of this embodiment are clamped and fixed at a position offset by 1 / 3 of the center point of the anode.

[0069] During operation, the overhead crane lifting ring 5 is connected to the clamp, and the clamp is lifted by the upward traction force, and then the clamp is lowered to the ground. The opener 401 can adopt the conventional opener structure in the prior art, that is, the opener 401 has a built-in spring, so that the lock head 403 under the opener 401 can be rotated 90°. When the lock head 403 of the opener 401 drops to the opener base 402, the lock head 403 rotates 90°, and when the lock head 403 is opposite to the baffle direction of the opener base 402, the lock head 403 is stuck, so that the clamp is in a normally open state. When the clamp is again pulled upward by the overhead crane, the ground staff grasps the handrail 304 and adjusts the clamp's gripping pin 202 to the appropriate position of the anode carbon block, generally using a position offset by 1 / 3 of the center point as defined above. The clamp then drops down to the limit position, causing the lock 403 of the shutter 401 to rotate 90° again. At this point, the lock 403 releases the locked limit, and the clamp completes the clamping. The overhead crane lifts upward and drives the clamp to perform a tensioning movement, causing the gripping pin 202 to clamp the anode carbon block. As the overhead crane slowly rises, the anode carbon block completes a 90° flip due to its own eccentricity, and the overhead crane finally stops rising.

[0070] In the above technical solution, the device for flipping the anode sampling fixture provided by the utility model has the following beneficial effects:

[0071] The device of the utility model can realize the clamping and transportation of the anode, and can replace the manual turning operation by eccentric grasping through the improved grasping nail 202, thereby eliminating the source of operational danger, improving work efficiency, and realizing multi-faceted sampling.

[0072] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
